Should you have any Equipment without Maintenance Plans?

Going by the principle of "as much as is necessary, but as little as possible" it seems that all Equipment in SAP in a plant must have a Maintenance Plan - otherwise why bother including it in the plant if you don't have plans to maintain it? Is this the right approach, or no?

Yes, I appreciate you can do whatever you want based on your organization's needs, but I am trying to understand what would be the "correct" principle/approach for "most cases".

If you don't add Equipment without Maintenance Plans, what do you do when you have an item that you don't think you will need to maintain, so it doesn't have an Equipment number, but one day it breaks down. For example, some pipe inside a wall starts leaking.

Now you must raise a Notification and a Work Order but there is no corresponding Equipment number for this pipe because it was decided that there is no Maintenance Plan for pipes inside walls so it wasn't added as an Equipment.

Would you ask the superuser to simply add the Equipment without a Maintenance Plan so you can record the Notification and Work Order?

Equipments can be deeply structured - one installed within another.

Maintenance plans usually make sense on some component level - thus no need for a maintenance plan for each and every equipment.

(Besides other reasons) some individual object needs to be represented as equipment if it might need maintenance (planned or unplanned) - thus being referenced from a maintenance notification and/or order.

Maintenance plans (as the name tells) are concepts for planned maintenance. In reality quite some unplanned maintenance is needed too.

Thank you for the response.

Adding unplanned work for Equipment with maintenance plan is not a problem. My question is about unplanned work on Equipment which physically exists in a Plant but wasn’t added previously because nobody expected there to be any maintenance activity for that Equipment.

In the example I mentioned, when building the building, it was assumed the pipes in the walls will last forever. Now there is a leak. Since the pipes aren’t in the Equipment structure for the plant, you can’t create a Notification or Work Order linked to it.

Would the correct approach for this be to add the pipes as Equipment without a Maintenance Plan (since they don’t plan on doing any planned maintenance after the leak is repaired), do the job and leave these pipes as Equipment without a Maintenance Plan?
